If you compare the pictures on the website to what Tamiya has to offer, you know it will be worth every penny. Just an example, if you look at picture nr 11, you can see that you can even opt to store the airplane in its hangar, that's the first time I see this on any kit.
I believe the pricetag will be around 90 dollar or something, difficult to say with the dollar being less than the euro on one hand, but modelling supplies at your side being cheaper than here.
Anyone, yes, it is yet another bismarck, but hey, the armorguys have about a hundered Shermans and Tigers to choose from, the flyboys have the same thing with their Spitfires and Messerschmitts.
Besides, there are (hopefully) still new people joining (or re-entering) the hobby and even experienced people who have not yet built a Bismarck, isn't it great to have this detailed kit opposed to having to pay a higher price for the Tamiya kit and than even more for an aftermarket set just to make it remotely acceptable ?
